IRIX¨ 6.5.16 Update Guide 1600 Amphitheatre Pkwy. Mountain View, CA 94043-1351 Telephone (650) 960-1980 FAX (650) 961-0595

May 2002 Dear Valued Customer, SGI® is pleased to present the new IRIX® 6.5.16 maintenance and feature release. Starting with IRIX® 6.5, SGI created a new software upgrade strategy, which delivers both the maintenance (6.5.16m) and feature (6.5.16f) streams. This upgrade is part of a family of releases that periodically enhances IRIX 6.5. There are several beneﬁts to this release strategy: it provides periodic ﬁxes to IRIX, it assists in managing upgrades, and it supports all platforms. Additional information on this strategy and how it affects you is included in the updated Installation Instructions manual contained in this package. If you need assistance, please visit the Supportfolio™ Online Web site at http://support.sgi.com or contact your local support provider. In conjunction with the release of IRIX® 6.5.15, SGI added to the existing life cycle management categories the Limited Support Mode that customizes services we deliver to our users. This new support mode is targeted for open source products. We now offer eight (8) modes of

2 service for software supported by SGI : Active, Maintenance, Limited, Legacy, Courtesy, Divested, Retired, and Expired. Active Mode is our highest level of service. It applies to products that are being actively developed and maintained and are orderable through general distribution. Software fixes for all levels of problems can be expected. Maintenance Mode software is maintained and is still an important part of our product mix. No new functionality is added to products in this support mode. Functional fixes for severe problems are generally available. Products in this support mode category are still orderable through general distribution. Software usually stays in this category about 18 months before being moved to a mode of lesser support. Limited Mode is a restricted level of service developed mainly for products developed and maintained by open source organizations and that are distributed by SGI. Legacy Mode software generally runs on out-of-production operating system versions or system platforms that are no longer in active development or maintained. These products are usually distributed with limited availability. New support contracts may be offered and renewed. Services provided with Legacy Mode are limited to providing existing fixes and “workarounds” for reported problems. IRIX® 6.2, IRIX® 6.3, and IRIX® 6.4 operating system revisions are examples of major operating system releases that are supported in this category.

3 Courtesy Mode software is not ofﬁcially part of the software support offerings. Courtesy mode software is not covered by software support contracts, and call center support is not available. An e-mail alias may be provided to facilitate customer communications and to address any technical questions. Response times will vary according to availability of resources. The e-mail alias may be terminated at any time without advance notice. IRIS Showcase™ and Cosmo Worlds™ are examples of products with Courtesy Mode support. Divested Mode software has been turned over to a third party who assumes all responsibility for support. SGI no longer distributes these products. Calls received at the SGI Call Center for support on divested products will be redirected to the applicable third party. CA Unicenter® TNG and Syntax TAS™ are examples of divested products. Retired Mode provides restricted support for older software products which are no longer generally distributed by SGI. This level of support has severe limitations on portability to new platforms. Availability of support at this level is limited to existing customers with whom we have existing contractual obligations. This is the ﬁnal stage before a product is completely removed from the SGI product set. Expired Mode software products have reached the end of their useful life. These products are not supported or distributed in any form by SGI. Examples are: IRIX® 5.3, IRIXPro™, and Proconf.

4 The Web page at http://support.sgi.com/irix/news/index.html#swmodes contains a link to a Web page where the eight software support modes are described in more detail. This Web page also contains links to the latest customer letters, which provide a list of the various software products that have changed support modes. We thank you for your continued commitment to SGI. Terry Oberdank

5 Welcome to your SGI IRIX 6.5.16 update. This booklet contains: • A list of key features in IRIX 6.5.16 • A list of CDs contained in the IRIX 6.5.16 update kit • A guide to SGI Web sites

6 IRIX 6.5.16 Key New Features

The following changes have been incorporated into the core IRIX 6.5.16 overlay CDs and the Applications CD.

New Software Features - Feature Stream Only Filesystems • New option for XVM show command For the IRIX 6.5.16f release, the -extend option has been added to the XVM show command. Specifying this option will display additional information about physvols, slices, stripes and foreign disks than the show command alone. The XVM Volume Manager Administrator’s Guide and the XVM help screens have been updated with examples that use this option. • CXFS new features For IRIX 6.5.16f, CXFS features include the following: – Support for multiple operating system (multiOS) clients, such as Solaris nodes and Windows NT nodes. The CXFS GUI and cmgr(1M) command now allow you to specify the operating system for a given node.

7 – I/O fencing, which allows a problem node to be isolated from the storage area network (SAN) so that it cannot corrupt data in the shared CXFS filesystem; this is required for Solaris nodes and Windows NT nodes. A Brocade switch is required to support I/O fencing. – Support for a two-node CXFS cluster running with FailSafe and an L1 controller on Origin 300 and Origin 3200 systems. See the CXFS Software Installation and Administration Guide for more information. • CXFS upgrade: filesystem definitions The structure of the CXFS filesystem configuration was changed with the release of IRIX 6.5.13f. Backward compatibility with earlier versions is no longer maintained as of IRIX 6.5.14f, since all nodes in the cluster must be running the same or adjacent releases. – If you are upgrading from 6.5.13f to 6.5.14f or later, there is no further impact. – If you are upgrading from 6.5.12f or earlier, you must perform a one-time manual conversion of your CXFS filesystem definitions. See the CXFS Software Installation and Administration Guide for more information. • CXFS upgrade: cluster nodes For CXFS customers, if you install IRIX 6.5.16f including sysadm_base on a cluster node where the 6.5.13f or earlier version

8 of CXFS is installed, you will need to upgrade to the 6.5.16f version CXFS (sysadm_cxfs) and install 6.5.16f sysadm_cluster. System Performance and Tuning • New joblimitsign kernel tunable parameters group The IRIX 6.5.16 release adds the joblimitsign group of kernel tunables that can be used to specify that specific job limit resource accumulation and enforcement should be ignored by the kernel. Setting the kernel tunable value to 1 indicates the specific limit should be ignored. Setting the value to 0 will re-enable the limit for newly created jobs. The following kernel tunable parameters have been added: – jlimit_cpu_ign parameter The jlimit_cpu_ign parameter specifies that the accumulation and enforcement of CPU time limits for jobs should be ignored. – jlimit_data_ign parameter The jlimit_data_ign parameter specifies that the accumulation and enforcement of data memory limits for jobs should be ignored. – jlimit_nofile_ign parameter The jlimit_nofile_ign parameter specifies that the accumulation and enforcement of limits for the number of open files in jobs should be ignored.

9 – jlimit_numproc_ign parameter The jlimit_numproc_ign parameter specifies that the accumulation and enforcement of limits for the number of processes in jobs should be ignored. – jlimit_pmem_ign parameter The jlimit_pmem_ign parameter specifies that the accumulation and enforcement of physical memory limits for jobs should be ignored. – jlimit_pthread_ign parameter The jlimit_pthread_ign parameter specifies that the accumulation and enforcement of limits for the number of pthreads should be ignored. – jlimit_rss_ign parameter The jlimit_rss_ign parameter specifies that the accumulation and enforcement of resident set size (RSS) memory limits for jobs should be ignored. – jlimit_vmem_ign parameter The jlimit_vmem_ign parameter specifies that the accumulation and enforcement of virtual memory limits for jobs should be ignored. For more information on kernel tunable parameters, see the setjusage(2) entry in Appendix A in IRIX Admin: Resource Administration.

10 – New setjusage system call The setjusage system call is used to update resource usage for jobs in the kernel. The system call can only be used to update usage information if the limit accumulation and enforcement for the specified resource is being ignored. This function can be used by sites to implement a site-specific solution for resource accumulation and enforcement. Using this system call allows the various job limit status commands to display usage values as reported from the site-specific implementation. For more information, see the setjusage(2) man page and the setjusage(2) entry in Appendix A in IRIX Admin: Resource Administration. Comprehensive System Accounting (CSA) • Change to csa.conf file The IRIX 6.5.16 release removes the ACCT_FS parameter in the /etc/csa.conf file. The MIN_BLKS parameter now determines the minimum number of free 1K blocks needed on the file system on which the /var/adm/acct directory resides. The default is 2000. To ensure that the MIN_BLKS variable has been set correctly, check the value in the /etc/csa.conf configuration file. For more information, see Chapter 5, “Comprehensive System Accounting”, in IRIX Admin: Resource Administration.

11 New Software Enhancements - Maintenance and Feature Stream Kernel Conﬁguration • New interrupt thread control interface IRIX 6.5.16 supports a new XThread Control Interface (XTCI) that allows users to control many interrupt thread parameters, including cpu binding. System administrators can use this interface to control kernel thread properties separate from the physical interrupts they service. For information on this interface, see the realtime(5) man page. Performance Monitoring Tools • Enhanced rtmond performance for large systems For the IRIX 6.5.16 release, performance improvements have been made to the rtmond system monitoring daemon. These improvements will be most noticeable on systems with 128 CPUs and larger. For information on the rtmond daemon, see the rtmond(1) man page. Array Services • Features added to Array Services For the IRIX 6.5.16 release, Array Services scaling support has increased from a maximum of 8 hosts to 64 hosts. Array Services also provides increased interoperability with job limits and new functions such as askillash. For more information, see the Array Services

12 release notes and the array_services(5) man page and the “Array Services” chapter in IRIX Admin: Resource Administration. Graphic Workstations • Enhanced mouse support IRIX 6.5.16 provides support for mice with more than three buttons and mice with wheels. Users with Microsoft Intellimouse or Intellimouse Explorer can use this expanded functionality in many IRIX and Open Source applications. For information on this feature, see the pcmouse(7) man page. CPU Management • New option to mpadmin(1) command The IRIX 6.5.16 release adds an -x[processor] option to the mpadmin(1) command that allows you to exclude the speciﬁed CPU from performing any work. This functionality is useful in a situation in which you suspect a CPU may have a hardware error but you do not want to shut down your entire system. For more information, see the “Excluding a CPU from Performing Work” section in IRIX Admin: System Conﬁguration and Operation and the mpadmin(1) man page.

13 Checkpoint and Restart • New options to cpr command The IRIX 6.5.16 release includes two new options to the cpr command: – The IRIX 6.5.16 release includes the cpr -w option that allows you to use the attribute file located in the current working directory (versus $HOME/.cpr). For more information, see the IRIX Checkpoint and Restart Operation Guide and the cpr(1) man page. – The IRIX 6.5.16 release includes a new -m memory migration option to the cpr command, which allows you to migrate the checkpointed memory to the location in the system topology where the restart operation is executing; for example, within a specific cpuset or within the global cpuset. In addition, a new CKPT_RESTART_MIGRATE restart-related flag has been added for use with the ckpt_restart() library interface function.

These enhancements to the cpr command and ckpt_restart() library interface provide better functionality when restarting processes within cpusets. For more information on the cpr -m option, see the IRIX Checkpoint and Restart Operation Guide and the cpr(1) man page.

14 • New CONTENTS action keyword for FILE policy of CPR attribute file The IRIX 6.5.16 release adds a CONTENTS action keyword for the FILE policy of a CPR attribute file. This causes the system to calculate checksum (currently MD5) on the file at checkpoint. Upon restart, the system detects if the file has been modified between begin-of-file and file-size-at-checkpoint; if the file has been modified in this area, the process is refused restart, otherwise, it seeks to the previous offset and continues. For more information, see the IRIX Checkpoint and Restart Operation Guide. System Availability • IRIX 6.5.16 and FailSafe 2.1.2 For FailSafe customers, if you install IRIX 6.5.16, including sysadm_base, on a cluster node where FailSafe 2.1.1 is installed, you will need to upgrade to FailSafe 2.1.2 (sysadm_failsafe2) and install 6.5.16 sysadm_cluster. Scalability • New functions in Cpuset library The IRIX 6.5.16 release adds two new functions in the Cpuset library called cpusetMove(3x) and cpusetMoveMigrate(3x). These Cpuset library routines can be used to move processes between cpusets and optionally migrate their memory. They allow you to move specific processes, or groups of processes, between existing

15 cpusets, and out of a named cpuset into the pool of CPUs not assigned to any specific named cpuset. Using this functionality, you can easily destroy existing cpusets to free resources to run a prime job and then easily reconstitute cpusets to continue prior jobs. Because memory used by a process can be migrated to the node associated with the new cpuset, memory locality is improved. For more information on the cpusetMove(3x) and cpusetMoveMigrate(3x) routines, see Chapter 4, “Using the cpusetMove and cpusetMoveMigrate Functions” in the IRIX Admin: Resource Administration manual and the cpusetMove(3x) and cpusetMoveMigrate(3x) man pages. Semaphore Devices • New systune variable in usopenpollsema(3P) library call The IRIX 6.5.16 release adds a disable_uspollsema_chk systune variable for the usopenpollsema(3P) library call. This variable turns off the standard access mode checking on usopenpollsema(3P) (set on the first call to usopenpollsema(3P) via the acc parameter). Some older IRIX applications that were written to work with usopenpollsema(3P) may now require this variable. For more information, see the usopenpollsema(3P) man page and the /var/sysgen/mtune/kernel configuration file.

16 System Performance and Tuning • New kernel tunable parameters The IRIX 6.5.16 release adds documentation for the following kernel tunable parameters: – min_bufmem general parameter min_bufmem specifies the minimum amount of memory held by filesystem metadata that is cached in the buffer cache when the system runs into low memory conditions. – rtcpus dispatch parameter rtcpus controls the quality of the real-time scheduler. – bdflush_interval filesystem parameter bdflush_interval specifies the interval at which the bdflush function executes to push dirty file data to disk. For more information on kernel tunable parameters, see Appendix A in IRIX Admin: System Configuration and Operation. Licensing Software • Upgrading to the FLEXlm 8.1a release from Globetrotter Software, Inc. IRIX 6.5.16 provides support for upgrading license_eoe to the FLEXlm 8.1a release from Globetrotter Software, Inc. The license manager daemon is built in V5 compatibility mode. For more information see the FLEXlm End User Manual and the associated man pages.

17 IRIX 6.5.16 also provides support for upgrading license_dev to include new optional thread-safe FLEXlm 8.1a client side libraries and headers. For more information see the license_dev release notes. Online Documentation • Planned Online Documentation Tools/Books Upgrade in IRIX 6.5.17 For the IRIX 6.5.17 release, the online documentation tools (InSight) and books will undergo some changes. A more open, standards-based technology will be utilized to create HTML books from industry-standard DocBook XML markup. This same technology will be provided to ISVs and customers, allowing them to create similar books. An update process will be supplied to make existing books available in the new format. InfoSearch will become the primary documentation viewing tool and will be modeled after the SGI TechPubs Library (http://techpubs.sgi.com), which already utilizes the new book format. Books will also be viewable directly from the ﬁlesystem using any available web browser. More detailed information regarding this upgrade will be made available in the IRIX 6.5.17 Welcome web page.

26 Key New Features from IRIX 6.5.1 to IRIX 6.5.15

Hardware Platforms and Features Supported Introduced in IRIX 6.5.15: • Support for the SGI Origin 300 server series. This includes support for the Origin 300 Base Module in 2, 4, and 8 processor sizes, the addition of a NUMAlink Module for scaling up to 32 processors, and the TP900 Storage Module. Introduced in IRIX 6.5.13: • Support for the 500MHz R14K processor on SGI Origin 2000 and Onyx2 systems Introduced in IRIX 6.5.12: • Support for the 500MHz R14K processor on SGI Origin 3000 series and Onyx 3000 systems Introduced in IRIX 6.5.9: • Support for the SGI 3000 series of servers, including the SGI 3200, SGI 3400, and SGI 3800 servers • Support for the TVO digital video option board for Silicon Graphics Onyx2 systems • Support for the QED RM7000 processor on O2 systems

27 Introduced in IRIX 6.5.8: • Support initiated for VPro Graphics, the next generation graphics for Silicon Graphics Octane systems Introduced in IRIX 6.5.7 • Support for Silicon Graphics Onyx2 InﬁniteReality3 systems • R12000S CPU on SGI 2200, SGI 2400, SGI 2800, SGI 2100, and Origin 200 Introduced in IRIX 6.5.5: • QLA2200 (copper and optical) is supported for FC-AL, FC-AL via the Emulex hub, or fabric attach via the Brocade Silkworm 2000 switches Introduced in IRIX 6.5.4: • 270-MHz processor for Silicon Graphics O2 and Silicon Graphics Octane visual workstations • HDTV XIO Board for Silicon Graphics Onyx2 and SGI Origin 2000 systems (this now includes the former Cray Origin 2000 system) Introduced in IRIX 6.5.3: • Systems using the MIPS R12000 processor • Digital Video Multiplexer option board (DPLEX) for Silicon Graphics Onyx2 systems • Redundant Power Supply (RPS) • 21" Monitor Support for O2 and Octane systems

28 Introduced in IRIX 6.5.2: • Flat Panel Monitor for O2 systems • 16-pipe Onyx2 InﬁniteReality systems • GSN network adapter Introduced in IRIX 6.5.1: • Gigabit Ethernet for Octane and SGI Origin systems • 128p Metarouter for Origin 2000 systems (formerly known as Cray Origin 2000 systems) • Dual Channel Display option for O2 systems • Onyx2 InﬁniteReality2 systems • 225QC for SGI Origin 200 systems

New Software Features-Feature Stream Only Introduced in IRIX 6.5.15 • For the IRIX 6.5.15f release, the default naming convention for XVM subvolumes in the /dev/lxvm/ and /dev/cxvm directories is volname, subvolume. Older releases of XVM created a directory entry for a subvolume of the form volname_subvolname. This convention can yield potential problem. For example, since vol1_data is a legal name for a volume

29 it is impossible to determine whether /dev/lxvm/vol1_data refers to the data subvolume of the volume vol1 or to a volume named vol1_data. The volname_subvolname form of subvolume directory entries is still supported in IRIX 6.5.15f, but its use is not recommended. For information on XVM device directories and pathnames, see the XVM Volume Manager Administrator’s Guide. • For the 6.5.15f release of IRIX, you can implement disk quotas on XFS ﬁlesystems according to group ID. Previous releases of IRIX supported implementing quotas according to user and project ID. Project and group accounting are mutually exclusive. This feature is on-disk compatible with Linux-XFS group accounting, where this feature is already active. For information on administering XFS quotas, see IRIX Admin: Disks and Filesystems. Caution: Group quotas are supported in the feature stream only. If you implement group quotas on a disk and, subsequently, mount that disk with the pquota mount option on a machine running the maintenance stream or an earlier release of the feature stream on which group quotas are not supported, the quota accounting could be corrupted.

30 • IRIX 6.5.15f provides the following new features for CXFS. – Support has been added for clients of other operating systems such as Solaris as defined in CXFS Client Administration Guide. These clients are released asynchronously from the IRIX release. This support requires IRIX 6.5.15f plus appropriate patches. For more information, contact your SGI support contact. – Default scripts are now provided in the /var/cluster/clconfd-scripts directory to permit NFS-exporting of CXFS filesystems listed in /etc/exports. – Changes have been made to the rotatelogs script syntax. The root crontab file now has an entry to run the rotatelogs script weekly. If you run the script twice in one day, it will append the current log file Introduced in IRIX 6.5.14 • The CXFS GUI was enhanced in the IRIX 6.5.14 release as follows: – CXFS Manager and CXFS Cluster View windows are now combined into one window called CXFS Manager. – Tasks can now be launched by clicking the right mouse button over the tree-view area, or by selecting Tasks on the menu bar. – Command line interfaces (CLIs) that the GUI runs can be viewed from a new File > Show SALog menu item.

31 – You can now partially mount filesystems on just a subset of nodes, using the Define Filesystem and Modify Filesystem tasks. – A new Find text field helps you find items within the displayed tree-view area. Filesystem status and cluster status update faster. For more information, see the CXFS Software Installation and Administration Guide. • The structure of the CXFS filesystem configuration was changed with the release of IRIX 6.5.13f. Backward compatibility with earlier versions is no longer maintained as of IRIX 6.5.14f, since all nodes in the cluster must be running the same or adjacent releases. – If you are upgrading from 6.5.13f to 6.5.14f or later, there is no further impact. – If you intend to run a mixture of 6.5.13f and 6.5.14f nodes, you must turn off backward compatibility. – If you are upgrading from 6.5.12f or earlier without first installing and running 6.5.13f, you must perform a one-time manual conversion of your CXFS filesystem definitions. See the CXFS Software Installation and Administration Guide for more information.

32 • For CXFS customers, if you install IRIX 6.5.14f including sysadm_base on a cluster node where the 6.5.13f version of CXFS is installed, you will need to upgrade to the 6.5.14f version CXFS (sysadm_cxfs) and install 6.5.14f sysadm_cluster. Introduced in IRIX 6.5.13 • With 6.5.13, the structure of the CXFS filesystem configuration has been changed. CXFS filesystems can now be defined, modified, managed and deleted independently of each other, and of the cluster definition. (Previously, the CXFS filesystems were defined as attributes to the cluster definition.) To accommodate clusters mixing nodes running 6.5.12 and 6.5.13, backwards compatibility is enforced by default in 6.5.13. For more information, see the CXFS Software Installation and Administration Guide. • The XVM Volume Manager can be used when layered with the CXFS filesystem. The XVM Volume Manager can also be used as a standalone volume manager; this requires that you be running the 6.5.13f release leg of the IRIX operating system. The 6.5.13m leg does not support XVM as a standalone volume manager; this support will be added in a later release. For information on CXFS filesystems, see CXFS Software Installation and Administration Guide.

33 • Added support for the use of mirrors in XVM logical volumes. The mirroring feature of XVM requires the XFS Volume Plexing software option. Customers running CXFS and who want to run mirrors will need to purchase this license. XLV customers with plexing licenses can upgrade to XVM without having to acquire a new license. Introduced in IRIX 6.5.12 • Supports the labeling of disks as XVM system disks in the XVM Volume Manager. For information on XVM system disks, see the XVM Volume Manager Administrator’s Guide. Introduced in IRIX 6.5.10: • XVM installed with CXFS is now qualiﬁed on IP35 (Origin 3000) systems in addition to the existing qualiﬁcation on the IP27 (Origin 200, Origin 2000, and Onyx2) and IP30 (Octane) systems. Introduced in IRIX 6.5.9: • CXFS supports the use of hierarchical storage management (HSM) products through the data management application programming interface (DMAPI). • CXFS and IRIS FailSafe 2.1 can be installed and run on the same system, which is known as coexecution. Note: The CXFS and FailSafe coexecution feature is not available in the IRIX maintenance stream. IRIS FailSafe 2.1 is an independently shipped product and is not shipped with IRIX.

34 • Support for the Scheduled Transfer Protocol (STP). For more information, see the stp(7P) man page or http://www.hippi.org. • Support for disk quotas that can now be set by project ID. For more information on disk quotas and their administration, see IRIX Admin: Disks and Filesystems. For more information on project IDs, see IRIX Admin: Backup, Security, and Accounting. For more information on the administration of disk quotas by project, see the edquota(1M), find(1M), quota(1M), repquota(1M), and fstab(4) man pages. • Support for the waitjob feature, which includes the new functions setwaitjobpid() and waitjob(). For more information, see IRIX Admin: Resource Administration and the waitjob(1M) and setwaitjobpid(1M) man pages. Introduced in IRIX 6.5.8: • Support for Comprehensive System Accounting (CSA). For more information, see IRIX Admin: Resource Administration and the csa(1M) man page.

35 Introduced in IRIX 6.5.7: • Support for job limits Job limits allow system administrators to manage user access to system resources by setting limits on different system usage parameters. For more information on the usage of the different system usage parameters, see the IRIX Admin: Resource Administration Guide and the following man pages: jstat(1), jlimit(1), job_limits(5) genlimits(1M), and showlimits(1). • Support for the CXFS product CXFS provides a cluster ﬁle system that allows ﬁle sharing between machines. CXFS requires a new volume manager, XVM. The IRIX 6.5.7 release version of CXFS contains metadata server recovery. See the CXFS Software Installation and Administration Guide for the administrative shutdown procedures and additional troubleshooting information. The Caveat and Release Note Updates link at http://support.sgi.com/6.5/caveat_updates.html should be checked periodically for information on the latest CXFS and XVM patches, descriptions of implemented CXFS and XVM features, updated Release Notes, or any late-breaking caveats.

36 Introduced in IRIX 6.5.6: • Support for the Scheduled Transfers (ST) protocol. In this initial release of ST, only the Gigabyte System Network (GSN) network adapter is supported. Introduced in IRIX 6.5.2: • Motif 2.1/IRIS ViewKit 2.1 • IRIX Oplock support • Support for non EUC encoding and locales (sjis/big5/gbk/utf8)

Maintenance and Feature Streams Introduced in IRIX 6.5.15: • XFS inode numbers are 64-bit values containing an encoded disk location. For large filesystems (1 Terabyte plus), the inode numbers can overflow into the top 32 bits of the number. Certain backup applications which use the inode number only allow 32 bits of space, and thus have severe problems dealing with very large XFS filesystems. As of IRIX 6.5.15, XFS has been changed to allocate inodes only within the lower portion of the filesystem to avoid this overflow issue. Other allocation policies in the filesystem will make this lower order space preferred for inodes and reduce the risk of a filesystem refusing to create new inodes when it still has space available.

37 For existing large filesystems with high numbered inodes this does not solve the problem, but it does solve it for new filesystems, and for new files created on existing filesystems. For backwards compatibility a new mount option is available, inode64, this will allow xfs to place inodes anywhere in the filesystem and follow exactly the original placement policies. Filesystems which were small enough not to be able to overflow 32 bits of inode number also retain the old behavior. • The 6.5.15 release of IRIX adds support for disks that have a capacity of 2 terabytes. Previously, the maximum was 1 terabyte. The maximum disk capacity had become an issue with the introduction of 180GB drives, multiples of which can be combined into a single logical unit (lun) behind a RAID controller. The maximum capacity of a logical unit for both of our current RAID controllers is 2 terabytes, so this change allows us to support that maximum. • For the IRIX 6.5.15 release, Chapter 5 “System Administration in a Multiuser Environment” in IRIX Admin: System Configuration and Operation has been updated with a new section on Project ID numbers and the chproj(1) command that changes the project ownership of a file. The project ID may be either a project name found in the project file, or a decimal project ID. For more information, see the chown(1) man page and the IRIX Admin: System Configuration and Operation manual.

38 • In IRIX 6.5.15, the systune parameter gang_sched_off is turned on by default. This means that gangs will not be running on the system unless the system administrator sets gang_sched_off to 0. This differs from previous IRIX releases, for which gangs ran on the system automatically. This change has been made per field request because we have discovered that having gang scheduling on by default greatly diminishes system performance. Most customers have been running with it off. • The IRIX 6.5.15 release adds a coremask parameter set in the /var/sysgen/mtune/kernel file to determine what kind of permissions a core file will receive. Currently, when a process creates a core file, it uses the umask of the owner of the process to determine the permissions. This can lead to core files containing sensitive information being created with world readable permissions. This systune variable allows the system administrator to limit access to core files. The default is 0, which is the current behavior. However, if the coremask variable is set to some other value, it uses that number as the umask and ignores the umask of the owner of the process. For example, if coremask is set to 0177 and the owner of the process has a umask of 022, the permissions set on the core file will be 600 instead of 644. This variable assumes that the number entered is octal. The default setting is 0. The minimum setting is 0. The maximum setting is 0177.

39 For more information on the coremask parameter, see Appendix A, “IRIX Kernel Tunable Parameters”, in IRIX Admin: System Configuration and Operation. • A new partitioning administration command, partmgr(1M), is available to define and store partition definitions. For more information, see IRIX Admin: System Configuration and Operation. • The IRIX 6.5.15 release adds support for the /dev/poll interface for scalable and efficient event notification. For information on /dev/poll, see the poll(7M) man page. • For the IRIX 6.5.15 release, the DHCP client (proclaim) has been updated to include options to allow DHCP clients to capture changes to DNS, NIS, or GATEWAY in your environment. For more information, see the proclaim(1M) man page and IRIX Admin: Networking and Mail. • The IRIX 6.5.15 release provides the ability to designate one or more CPUs or a range of CPUs on a single line in the cpuset configuration file. The CPUs in a cpuset configuration file do not have to be specified in a particular order. The following is a sample configuration file that describes an exclusive cpuset containing 7 CPUs:

40 # cpuset configuration file EXCLUSIVE MEMORY_LOCAL MEMORY_EXCLUSIVE CPU 16 CPU 17-19, 21 CPU 27 CPU 25 For more information on the cpuset configuration file, see Chapter 4, “Cpuset System”, in IRIX Admin: Resource Administration. • For the 6.5.15 release, the systune(1M) man page has been updated to describe a situation where the system segment size value (syssegsz) reported by the systune command is different than the value set in the /unix file. Origin 300 Systems • The IRIX 6.5.15 release introduces support for the PCI Expansion Module to Origin 300 systems. The PCI Expansion Module allows PCI expansion on an Origin 300 independent of the addition of additional CPUs and memory. Each PCI Expansion Module adds 12 PCI slots and up to 4 PCI Expansion Modules to the system overall. • Starting with the IRIX 6.5.15 release, each partition of a partitioned Origin 3000 system will have a new unique FLEXlm host ID (lmhostid). Any FLEXlm license based on the old non-partitioned lmhostid value will no longer work and a new license key must be generated. See the following web page for additional details: http://www.sgi.com/support/licensing/.

41 – Contact the applicable software product vendor and provide the lmhostid number of the partition to generate a new license key. For nodelock licenses, provide the lmhostid for all partitions of the software installed and operating. – For software licensed by SGI, see the following web page for more details: http://www.sgi.com/support/licensing/. – For email and telephone contact information, see the IRIX 6.5.16 Welcome page and follow the “Bundled software and licenses” link. • For IRIX 6.5.15 we added HOTPLUG attach and detach support for SGI Gigabit Ethernet Network adapters. This feature is supported on IP35 Origin 3000 series systems only; it is not supported on IP35 0300 systems. For information on this feature, see IRIX Admin: Networking and Mail. • The IRIX 6.5.15 release supports the lmparthostids and lmbasehostid commands. The lmparthostids command generates a list of all 63 partition speciﬁc hostids and the unpartitioned id. This list can be passed to a license key generation tool for nodelock licenses so that the license works across all partitions or an unpartitioned system. The lmbasehostid command takes any arbitrary lmhostid (this could be a partition speciﬁc value) and generates the base unpartitioned id. That number could be used when the base lmhostid is required, even from a partition.

42 • The IRIX 6.5.15 release provides updated FLEXlm v7.2i support from GLOBEtrotter Software, Inc. The license manager daemon and the floating license server are built in V5 compatibility mode. For backwards compatibility, the client libraries and header files are still based on FLEXlm v6.1g. For more information, see the FLEXlm End User Manual and the associated man pages. Introduced in IRIX 6.5.14: • In the IRIX 6.5.5 release, SGI introduced a new optional directory format for XFS filesystems, referred to as the "version 2" directory format in mkfs output. XFS filesystems with a version 2 directory format can provide improved reliability and performance over filesystems with a version 1 directory format in some applications, particularly for applications that use NFS exported XFS filesystems. The directory format for an XFS filesystem is specified with the -n parameter of the mkfs command. The default directory format is currently the original version 1 directory format. Beginning with the IRIX 6.5.14 release, version 2 directories of XFS will be the default for all new filesystems created with mkfs. Version 1 directory filesystem creation will still be supported, but this will require that you specify the -n version=1 parameter of the mkfs command.

43 SGI recommends that all new XFS filesystems be created with version 2 directories. IRIX releases older than IRIX 6.5.5, however, will not be able to mount a filesystem created with a version 2 directory and will issue the following message when a mount is attempted: Wrong filesystem type: xfs Many SGI customers are currently running production servers with version 2 directories. If you want to format filesystems with the version 2 directory format prior to the 6.5.14 release, you can specify the following option of mkfs: mkfs -n version=2 There is no means for converting a filesystem, in place, between version 1 and version 2 directories. A filesystem can be converted between version 1 and version 2 directories by means of an xfsdump/mkfs/xfsrestore sequence. For more information, see IRIX Admin: Disks and Filesystems. •A-q cpuset_name -p option was added to the cpuset command that allows you to see the properties of particular cpuset, such as, the number of processes and CPUs associated with the specified cpuset. • The cpusetGetProperties() and cpusetFreeProperties() functions were added to the Cpuset System library. The cpusetGetProperties() function allows you to retrieve various properties associated with a cpuset. The cpusetFreeProperties() functions allows you to release the

44 memory used by a cpuset_Properties_t structure. Any programmer that uses the cpuset API from Irix 6.5.14, and later, can use these functions. For information, see chapter 4, "Cpuset System", in the IRIX Admin: Resource Administration manual and the cpusetGetProperties(3x) and cpusetFreeProperties(3x) man pages. • Parts of the IRIX Interactive Desktop were refreshed in IRIX 6.5.14. While functionality has not changed, the navigation, imagery, and graphics design have been enhanced in the following areas: – The main IRIX login window (clogin) has a new design using new SGI colors, font, and logo. The product is called sysadmdesktop and appears automatically at boot when root has chkconfig noiconlogin on. – EZsetup has a new layout and login icon using new SGI colors, font, and logo. The product is called sysadmdesktop and is launched by logging into EZsetup account from main IRIX login window. – The System Manager main window uses new SGI colors, font, and logo. The product is sysadmdesktop and is launched from the System toolchest. – The Welcome to SGI web pages have new navigation and new SGI colors, font, and logo. The product is Welcome. Launch from Find toolchest, select WhatsNew, double-click the Welcome_to_SGI icon.

45 – The Background Setting panel includes seven new desktop patterns using the new SGI logo and font: Camouﬂage, Citrus Citrus, Iron, Midnight, Reef, Sand, and Sprinkle. Note: You may notice slow performance when previewing all but the Sprinkle background, but not when switching desks (see the background(1) man page). Old backgrounds are still available. The product is desktop_eoe and is launched from the Desktop toolchest, select Customize, then Backgrounds. Introduced in IRIX 6.5.13 • The xfsrestore command returns an incorrect exit code when it encounters a media error; improving this process lets a system administrator intelligently react to these conditions. • Improved exit codes for the xfsrestore and xfsdump commands. This lets a system administrator correctly respond to end-of-media or operator interrupt conditions. • Changed the mkfs command to allow you to specify the size of an XFS allocation group, as an alternative to specifying the total number of allocation groups. You use the -d agsize= option for this. For information, see the mkfs_xfs man page and IRIX Admin: Disks and Filesystems. • Changed the mkfs command to allow you to specify the size of a stripe unit and the size of a stripe width in bytes or in ﬁlesystem blocks, as an alternative to specifying these values in 512-byte block

46 units. You use the -d su= and the -d sw= options for this. For information, see the mkfs_xfs man page and IRIX Admin: Disks and Filesystems. • Changed the default size of an XFS allocation group; larger filesystems will result in larger default allocation group sizes. • The xfsdump and xfsrestore commands will provide the VSN of the tape that reached its end-of-volume (or the VSN of a new tape that needs to be mounted) and pass this VSN to the media_change_alert_program specified with the -c option. This lets system administrators send commands to a tape jukebox to mount the next tape. • Changed the default size of an XFS log. The default log size grows with the size of the filesystem up to the maximum log size, 128 megabytes, on a 1 terabyte filesystem. For information on the default values of XFS allocation groups and XFS log sizes, see IRIX Admin: Disks and Filesystems. • Added cpusetAttachPID() and cpusetDetachPID() functions to the Cpuset System library. The cpusetAttachPID() function allows a programmer to attach a currently running program to an existing cpuset. The cpusetDetachPID() function allows a programmer to detach a currently running program to an existing cpuset. Any programmer that uses the cpuset API from Irix 6.5.13, and later, can use these functions. For information, see chapter 4, "Cpuset System", in the IRIX Admin: Resource Administration manual

47 and the cpusetAttachPID(3x)and cpusetDetachPID(3x) man pages. • The following features have been moved from Enhanced DHCP to standard DHCP: – Ping check before an address is leased to insure it is not already in use – MAC address ﬁltering; clients whose MAC address is listed in a ﬁle will be unable to obtain a lease and/or accesses from these clients will be logged. For more information, see the dhcp_bootp man page. • Added implementation of End Sequence to Scheduled Transfer Protocol. The upper layer protocol or applications can now terminate a transfer and restart another one without taking down virtual connection. • VPro for Octane/OpenGL performance improvements have been added as follows: – Improved X window performance by 25 percent based on x11perf – Improved performance of OpenGL glCopypixel() function • The following new system controller features have been implemented for the SGI Origin 3000 server series:

48 – Enabled router port security, which prevents unauthorized enabling of additional router ports on router bricks in the SGI Origin/Onyx 3400 server series – Enabled system serial number security, which prevents unauthorized changes to the system serial number – Completely redesigned the graphical interface for the front-panel display of the SGI 3400 and 3800 servers • Added hotplug attach feature that allows Gigabit Ethernet cards to be installed on a running system. A system administrator can use the pciconfig command to add cards to an Origin 3000 system and the ifconfig command to configure the cards for networking. For more information, see the pciconfig and ifconfig man pages. • Added Origin 3000 system partitioning support in the eoe.sw.partition software package. This feature improves how system partitioning software is installed, enabled, and disabled. It also eliminates the need to manually edit configuration files. • Efficiency improvements have been made to the BTE driver layer to reduce both latency and contention. This feature is a performance improvement to the existing functionality that is used internally by the system. • The tools that report CPU utilization have been modified to correct the sampling of %WIO to omit idle time in line with industry standards. See the sar(1) man page for details.

49 • Updated FLEXlm v7.2f support from GLOBEtrotter Software, Inc. The license manager daemon and the floating license server are built in V5 compatibility mode. For backwards compatibility, the client libraries and header files are still based on FLEXlm v6.1g. For more information, see the FLEXlm End User Manual and the associated man pages. Introduced in IRIX 6.5.12 • OpenGL Performer 2.4.1 execution environment • The IRIX tape-support feature consists of a tape support driver, personality daemons, and a daemon that manages the personality daemons.This release supports various devices including the Fibre Channel implementation on the StorageTek 9840 and T9940A tape drives. The reserve, release, preempt, clear, and prsv commands are available for these tape drives on the mt command. For more information, see the mt(1), tsarchive(1M), tsdaemon(1M), tserrpt(1M), tsset(1M), tsstop(1M), ts.config(4), and ts(7) man pages. • Updated FLEXlm v7.2e support from GLOBEtrotter Software, Inc. The license manager daemon and the floating license server are built in V5 compatibility mode. For backwards compatibility, the client libraries and header files are still based on FLEXlm v6.1. For more information, see the FLEXlm End User Manual and the associated man pages.

50 • The Scheduled Transfer Protocol (STP) has moved from the feature stream to the maintenance and feature stream. STP is now a mature supported protocol and it includes TRIX support. Introduced in IRIX 6.5.11: • Support for the use of a reserved area of memory; this reserved area is between virtual addresses 0x30000000 and 0x40000000. This feature disables the reserved area of memory that the kernel provides for applications to place their mmap and shmat mappings. For more information, see the mmap(2), shmat(2), syssgi(2), and sgi_use_anyaddr(1) man pages. • Support for weightless pthreads; they allow you to lower the priority of a process by using the npri -w command. For more information, see the npri(1) man page. • Support for upgrading license_eoe to the FLEXlm 7.1 release from Globetrotter Software, Inc. The license manager daemon will be built in V5 compatibility mode. For more information, see the FLEXlm End User Manual and the associated man pages. • Support for an increased maximum number of logical unit numbers (LUNs) in the SCSI infrastructure from 64 to 255. This change impacts only the fcadp and qlfc ﬁbre channel drivers and they will now enforce this LUN limit. If a LUN is greater than 255, it will be ignored after issuing a message to this effect. If you use large numbers of LUNs, you can exhaust the hardware graph. You may need to use the

51 systune command to increase the hwgraph_num_dev parameter to let the kernel build larger hardware graphs. • Support for licensing of partitioned environments. For more information, see IRIX Admin: Software Installation and Licensing. • Support for the PCI Hot Plug infrastructure on the SGI 3200, SGI 3400, and SGI 3800 servers.For more information, see the pciconfig(1) man page for specific administrative options. • Support for HP LaserJet 4050 and HP LaserJet 8100 printers • OpenGL Performer Runtime 2.2.11 overlay incorporates the latest fixes.
